Abstract

152 biopsy proven orbital lesions were seen during 1991-1995. Cystic tumors were the most frequent type of lesions, accounting for 36 cases(23.68%). Secondary tumors accounted for 17 cases(11.18%), lacrimal lesions 14 cases(9.21%), lymphoid tumors 14 cases(9.21%), inflammatory pseudotumors 13 cases(8.55%), peripheral nerve tumors 11 cases(7.24%), lipocytic and myxoid tumors 10 cases(6.58%), vasculogenic tumors 10 cases(6.58%), optic nerve and meningeal tumors 8 cases(5.26%), rhabdomyosarcomas 4 cases (2.63%), osteomas 3 cases (1.97%), metastatic tumors 3 cases (1.97%), histiocytic tumors 2 cases(1.32%), and other lesions 4 cases(2.63%). The most frequent primary orbital tumor was dermoid and most frequent maliganant tumor was maliganant lymphoma. In pediatric group, the most frequent primary orbital tumor was dermoid and most frequent maliganant tumor was rhabdomyosarcoma. Overall the frequency of maligant tumors was about 20%. Also this survey has a certain bias it will con tribute the recent classification and incidence of space-occupying lesions of the orbit in Korea.
